Alen T500

The Alen T500 comes with an intuitive design. It has a minimalistic and classy design that matches the earlier air purifier designs, which also fit most of your interiors because it comes in cool colors.

Additionally, it’s portable and compact. You can carry it for your camping trips at any given time. It stands at 22 inches and weighs 9 lbs. Nothing will stop you from packing it in that travel bag and hitting the road. What’s more, it can easily fit in smaller rooms which are not spacious.


Another feature that many homeowners would love is its average power usage. It consumes an average of 53 watts. Compared to other brands that consume up to 84 watts, you will indeed be relieved with the T500 power consumption. If you leave your air purifier on for eight hours a day, you will spend an average of $ 20 per year.


Don’t we all love devices that are easy to use? The T500 is easy to set up in just a few minutes. In addition, the controls are adjustable to ensure the air quality in a room is good.

HEPA Filter

Another amazing feature of the Alen T500 Tower air purifier is its 3-stage air filtration system which gives it the ability to capture a variety of airborne pollutants. It can seize bad smells, allergens, chemical contaminants, and microbes. So say goodbye to coughs, sneezing due to the high concentration of mold spores, pollen, and dust, and say hello to a transformed space with fresh air. The high-quality HEPA filter captures a high concentration of airborne contaminants. It has four filters which ensure that the air is clean and fresh. Its filters are designed to meet different cleaning needs.


The T500 cleans a small room coverage. It covers around 500 square feet. So if your home is more extensive or 500 square feet, the air cleaner will clean your whole home just once per hour. However, with 121 smoke and 159 pollen (cfm), it’s not adequate for keeping the air in your home clean enough.

Noise Level

As it cleans your room, the T500 air purifier has a high noise level. When it’s at its lowest speed, it produces 42db However, when it switched to its highest level, it produces 56db. To ensure a quiet environment, you can vary the cleaning methods to ensure low noise levels and clean air.

Filter replacement

For your filter to work efficiently, you need to replace it periodically. Unfortunately, replacing filters becomes expensive over time. The T500 air purifier has a replaceable and disposable filter. You will spend close to $30 every year replacing the filter. In addition, if the air filters are not returned from time to time, the filter will not work efficiently to clean the air in your home.


The T500 Tower air Purifier performs well, and it’s very affordable. However, its noise level is a bit high. It is one of the best cleaners and the lifetime warranty is something commendable.

Even though the air purifier lacks some modern features such as intelligent connectivity and intelligent sensor, which are standard features for other models within the same price range, it has excellent features. For instance, the LED indicator and the Timer are essential in the replacement of filters. While the elements are crucial, they are what you need to have the air purifier fully operational.

How to Use Alen T500

Keep it away from the Walls in a Flat Place

If you have never used an air purifier and are wondering how to use it, you need to know that the positioning of an air purifier is critical. Cleaners have front air intakes and side air intakes, and the outlets are located at the top. So, it would help if you placed your air purifier in a location that blocks air intake or any outlet. It should be 6 inches away from walls and objects. At this position, things will not stop air intake. Instead, it absorbs all allergens and microorganisms for a cleaner room.

The location should also not be humid for efficient cleaning.

Ensure the windows and doors are closed

Air purifiers are designed for indoor use. First, ensure all the doors and windows are closed. Ventilation helps in the removal of pollutants indoors and stale air. At the same time, leaving the doors and windows open introduces new pollutants such as smoke, dust, and pollen. Or it can remove clean air.

Always remember that air purifiers work efficiently in closed spaces. It removes microorganisms and allergens efficiently and faster. Lastly, it distributes air in closed areas ensuring that you have an adequate supply.

Keep your air purifier on at all times

The air purifier should run at all times. However, for energy efficiency, ensure it’s at a slower speed. In addition, your air purifier may come with auto mode features that provide high-quality air in your whole home.

If sensors detect that there’s a high level of pollutants, the speed will automatically increase. The Alen T500 tower air purifier has four fan speeds which work faster at a higher level. Even at a high rate, it consumes less power and saves on your electricity bill.

Ensure that the filters are replaced regularly

Filtration systems have two to five filters. The T500 tower comes with a pre-filter which can be cleaned and replaced after a year. If they are well cleaned, they offer efficiency at all times.

Suppose the filter status indicator turns red; it’s time to replace the filter. It’s easy to replace the filter since the guidelines are usually handed to you, including your purchase price. You should regularly wash the cleaner’s body to wipe acceptable debris or dust using a microfiber cloth. Do not use a wet cloth since it can cause electrical shocks on the cleaner.

How to Maintain Alen T500

Just like an air conditioner, an air purifier needs to be maintained over time. One advantage of an air cleaner is that it’s not complicated to maintain, you don’t need a technician to clean. Instead, follow the above simple steps to clean your air purifier all by yourself.

Turn off the air purifier

You’ll need to turn off your air purifier and disconnect it from the power socket to clean it effectively and avoid power shocks.

Dismantle all the components

Open the air purifier and check out the parts. If you can pull to bits the air filter, move to the next step.

Clean the HEPA Filter.

The HEPA filters are designed to seize the smallest pollutants and trap them permanently. Therefore, the ability to trap those pollutants such as smoke, pollen, and dust effectively makes the HEPA filter the most critical component of a filter-embedded air purifier.

You need to clean this element carefully since it’s costly to replace. Keeping it clear and clean ensures proper working for a long time and ensures durability without constant replacement. In addition, smart sensors provide that the system is monitored, and it alerts you when you need to change the filter. It also lets you know the time left to replace the filter.

Once you have cleaned the HEPA filter, you should also clean areas around it and the whole air cleaner. Thereafter, return the parts effectively to ensure it works appropriately.

Other general considerations on usage and maintenance include:

  • Ensure that you place your air filter in a clean spot always.
  • Regularly check the filter indicator to see when you need to change the filter.
  • Check the permanent filter every week.
  • Clean the permanent filters as often as once in three months
  • Use a dry cloth to clean inside an air purifier.
  • Turn off the air purifier before you unplug it.
  • Do not use detergents or solvents to clean an air purifier.
  • Do not place anything on top of an air purifier.
  • Wash pre-filters as regularly as you can.
  • Ensure the air purifier is placed in a position where it can clean the air quickly.
  • Always replace a worn-out filter with a new filter. A life indicator on the filter will alert you when to replace the old one.

Frequently Asked Questions

Will the air purifier make the air around my whole home dry?

You don’t need to worry since air purifiers do not have dehumidifying factors. So it will not make the air dry. Humidity levels will remain the same in your home. It traps pollen, dust, and smoke particles by the use of micron air filters. If the air is dry in your home, get a humidifier that will improve the mood around your space. In addition, it will reduce nose bleeding cases.

My room is more than 350 sq. feet; can I still get the T500 air purifier?

The efficiency levels of any air purifier depend on the air exchange per hour or the number of times within one hour when the air is completely replaced. If an air purifier exchanges six times per hour, it’s very efficient. The T500 can clean your room, but the rate will be lower. However, the rate will not drop to lower levels, so; you will still receive allergen-free and fresh breathable air. If your room is smaller, then the T500 will efficiently clean your room.

Do I need an air purifier in every room?

Not at all. If you buy an air cleaner for every room, it will be costly. Again, your electricity bill will go up. Most cities are not heavily polluted, so an air purifier for every room is not necessary. If you must, consider getting air cleaners for rooms that primarily get odors, such as the bathroom, living room, and kitchen. Also, if a family member has a respiratory disorder, you can consider getting an air purifier in their room.

Should the Alen T500 air purifier run all the time?

Yes. This ensures the air purifier works efficiently. Air pollution occurs when air pollutants accumulate compounds and odors in the air around your home. To ensure clean air, you need to keep your air purifier running all the time.

If you need to cut down on your electricity costs, consider using natural methods to increase the air purifier’s efficiency. It’s also advisable to consistently run your air cleaner at low speed for low energy consumption. Other tricks you can use to ensure the air around your whole home are clean are to use non-toxic cleaning agents and cook with open windows.

You can also preset your air cleaner to increase the speed level if the air quality deteriorates in your home. In addition, the Alen T500 Tower air purifier consumes less power which will not increase your electricity bill.

Do I go for a pre-configured air purifier or a customizable option?

If you already know the kind of air cleaner you need and the HEPA filters that will meet your needs, you can pick the customizable option which allows the air purifier to meet your exact specifications. Pre-configured air purifiers are designed to help you avoid compositing air filters from the ground. Configured options are designed with different needs in mind, such as pet odors, allergies that have specific additional filters, and air purifiers to fit the job. What is important is that you can customize the options and choose different panels to suit your needs.

Does T500 use a lot of energy?

No, it’s energy efficient.


Alen T500 Tower air purifiers suits only and only the small rooms around 200 – 250 square feet or smaller. Unfortunately, 500 sq. ft. is a marketing trick and this air purifier won’t improve air quality in medium rooms.

It does clean air in small spaces, but the presented above alternatives (Winix, Coway, Honeywell) are cheaper in maintenance overall, so I recommend taking a look at them first (I reviewed them as well) before ordering the T500.
